THRESHlNG-MACHINE ATTACHMENT.

SPECIFICATION forming part of Letters ZPatent No. 658,567, datedSeptember 25, 1900.

Application filed October 14, 1899. Serial No. 733,630. (No model.)

To a, whom it may concern.-

Be it known that I, ELMER G. HOWARD, a citizen of the United States,residing at Grain Creek, in the county of Black Hawk and State of Iowa,have invented a certain new and useful Threshing-Machine Attachment, ofwhich the following is a specification.

My invention relates to threshing machines, and has for its object toprovide an attachment designed to be used in connection with a conveyerand is in the nature of a screen or shield to prevent the wind fromblowing the straw from the straw-carrier as it passes therefrom to thestacker.

With this object in view myinvention consists of a bow-shapedcollapsible frame covered by any suitable materialsuch as can vas,cotton, or the likewhich will be attached to the discharge end of thestraw-carrler.

My invention further consists of the parts and combination of parts tobe more fully described hereinafter, illustrated in the accompanyingdrawings, and recited in the claims, all forming a part of thisspecification.

In the drawings, Figure 1 is a perspective View of my invention appliedto a straw-carrier at its rear end, the straw-carrier being shown indotted lines. Fig. 2 is a rear View of the same. Fig. 3 is a sideelevation of the frame, to which the covering will be attached; and Fig.4 is a side elevation of the frame folded.

Referring now to the drawings by reference-numerals, 5 indicates anupwardly and forwardly extending bow-shaped member, to each side ofwhich are connected the rectangular frames 6 and 7, consisting of thetop and bottom bars 8 and 9 and the end bars 10 and 11. The end bar 11has an upwardlyprojecting extension 12, connected at its end 13 with thebow-shaped member 5,and the rectangular frame is connected to thismember 5 at 14 and 15. Pivotally secured to and projecting from thisrectangular frame are the top how 16 and the bottom bow l7 and one ormore intermediate bows 18, secured in a like manner. To the forward endof the top bow 16 and the top of the bow 5 are two cords 19 and 20.Connected adjacent to the connections of the cords 19 and 20 on thebowineniber 5 and extending rearwardly and finally merging into a singlecord 21 are two cords or cables 22 and 23.

24. is a rearWardly-extending cable or cord secured to a suitable eye25, although it is obvious that two cords may be employed, if desired,one secured at each end thereof.

After the structure heretofore described has been assembled a cover 26,of any textile fabric, will be secured to the forwardly-extending bowsand the rectangular frame, when the entire device will be complete andready for use.

In practice, as before stated, this device will be pivotally positionedto the rear end of the straw-carrier at 27, and as the device isbottomless the straw will be fed onto the stacker without in any wayinterfering with the operation of the straw carrier and stacker.

If for any reason it is found necessary to gain'access to the stacker, apull on the cord 21 will raise the forwardly-extendingpivotally-connected bows, as shown in dotted line in Fig. 3, and when itis desired to again let down these bows a pull on the cord 24: willeffect the desired result. In transporting the device it can becollapsed, as shown in Fig. 4.

Having thus fully described my invention, what I claim as new, anddesire to obtain by Letters Patent of the United States, is

1. In an attachment for straw-carriers, the combination, with twoframes, of a bow having its ends secured to the frames, and its middleportion extending above and to the rear thereof, a series of coveredbows pivotally secured at their ends to said frames, means for pivotallysecuring said frames to the sides of a straw-carrier, cords connectedwith one of the frames and with the top of the bow respectively,substantially as described.

2. In an attachment for straw-carriers, the combination, with tworectangular frames,

the rear end bars of each of which is perfo- 9 rated and extends abovethe top bar of the frame, of a bow, the ends of which are securedrespectively diagonally across each frame and to the top of the extendedend bars, a series of covered bows pivotally secured to the frames,bolts through-the perforations in the end bars for pivotally securingthe attachment to the end of a straw-carrier, and cords secured to oneof the frames and to the top of the bow, respectively, substantially asdescribed.
